I may be mis-understanding what you are doing here, but it sounds like you should be using barplot() rather than hist(), which is referenced in the "See Also" in ?hist. This would be preferred if you want individual counts or proportions (or percents) from specific groups without binning.

Where does the 'scale = "percent"' come from? I don't recognize that argument from the standard histogram plotting functions.

Oh, wait a minute, just found it doing a search. The Hist() function is in John Fox's Rcmdr. Please be sure to note this if you are using a function from a contributed package. It saves time and increases the likelihood of your getting a reply.

Also, I am guessing that the extraneous content here is the result of using MS Word as your e-mail editor? Please use plain text only, which is the defined format for this list and from reviewing the archive, has been pointed out to you previously by Frank Harrell and Ted Harding.
